U.S. Strikes Test Iran’s Will to Escalate

As Iran and the United States assessed the damage done by U.S. airstrikes in Syria and Iraq, the initiative suddenly shifted to Iran and its pending decision whether to respond or take the hit and de-escalate.

The expectation in Washington and among its allies is that the Iranians will choose the latter course, seeing no benefit in getting into a shooting war with a far larger power, with all the risks that implies. But it is not yet clear whether the varied proxy forces that have conducted scores of attacks on U.S. bases and ships — and that rely on Iran for money, arms and intelligence — will conclude that their interests, too, are served by backing off.

The Houthis, an Iran-backed rebel group that controls parts of Yemen, have continued to attack ships in the Red Sea despite a series of U.S. strikes, including one Saturday, meant to deter them.

Friday’s strikes were largely in retaliation for a drone attack by an Iran-backed militia that killed three U.S. soldiers in Jordan on Jan. 28. The United States hit back at that group and several other Iran-backed militias with 85 targeted strikes. In the aftermath, U.S. officials insisted there was no back-channel discussion with Iran, no quiet agreement that the United States would not strike directly at Iran.

“There’s been no communications with Iran since the attack,” John Kirby, a spokesperson for the National Security Council, told reporters in a call Friday night after the retaliatory strikes were completed.

But even without direct conversation, there has been plenty of signaling, in both directions.

President Joe Biden is engaged in a military, diplomatic and election-year gamble that he can first restore some semblance of deterrence in the region, then help orchestrate a “pause” or cease-fire in the Gaza Strip to allow for hostage exchanges with Israel and then, in the biggest challenge of all, try to reshape the dynamics of the region.

But it is all happening in an area of the world he hoped, just five months ago, could be kept on the back burner while he focused on competition with China and the war in Ukraine — and in the middle of a campaign where his opponents, led by former President Donald Trump, will declare almost any move a sign of weakness.

For their part, the Iranians have been broadcasting in public that they want to lower the temperature — on the attacks, even on their quickly advancing nuclear program — although their ultimate objective, to drive the U.S. out of the region once and for all, remains unchanged.

Their first response to the military strikes Saturday morning was notably mild.

“The attack last night on Syria and Iraq is an adventurous action and another strategic mistake by the American government which will have no result other than increasing tensions and destabilizing the region,” said Nasser Kanaani, a spokesperson for Iran’s Foreign Ministry.

Until Friday night, every military action by the U.S. has been calibrated and cautious, the hallmark of Biden’s approach. The deaths of the American soldiers forced his hand, though, administration officials said.

He had to make clear that the United States would seek to dismantle many of the capabilities of the groups that call themselves the “Axis of Resistance.” That’s a reference to the concept that unites a fractious, often undisciplined group of militias: opposition to Israel, and to its chief backer, the United States.

And the strikes, Biden’s advisers quickly concluded, had to aim at facilities used by Iran’s Revolutionary Guard force.

But the president made the decision to strike largely at facilities and command centers, without aiming to decapitate the force’s leadership or threatening Iran directly.

There was no serious consideration of striking inside Iran, one senior administration official said after the first round of strikes was complete. And the telegraphing of the hit gave Iranians and their proxies time to evacuate senior commanders and other personnel from their bases and disperse them in safe houses.

To Biden’s critics, this is too much calibration, too much caution.

“The overriding intellectual construct of Biden foreign policy is avoidance of escalation,” said Kori Schake, a former defense official in the George W. Bush administration who directs foreign and defense policy studies at the American Enterprise Institute.

“They are not wrong to be worried about escalation,” she said. “But they don’t take into account that it encourages our adversaries. We often seem more worried about fighting wars we can win, and that encourages them to manipulate our fear.”

For Schake, who was an early leader of the “Never Trump” camp of Republican national security officials, there is a middle ground between attacking Iran and focusing on the proxy groups, including Kataib Hezbollah and the Houthis, that have struck U.S. forces. Biden could make clear, she said, that officers of the Revolutionary Guard “are targets anytime they set foot outside of Iran.”

But Iran’s leaders have indicated that they will retaliate for such attacks, as they did after Trump ordered the assassination of Gen. Qassem Soleimani, commander of the Revolutionary Guard’s most elite unit, the Quds Force, in Baghdad in 2020. “If an oppressive and bullying power wants to bully,” Iran’s president, Ebrahim Raisi, said Friday, “the Islamic Republic will deliver a stern answer.”

Biden’s decision to mount the strike with B-1B bombers that took off from the continental United States carried its own message: While Pentagon officials said the B-1Bs were the best bomber available for the complexity of these strikes, they were also the same warplanes that would be used in any attack on Iran’s nuclear facilities, should Iran decide to make a final sprint for a nuclear weapon. Nothing reminds Iran of the reach of American power more than a strike next door, one official said Saturday morning.

What seems overcautious to some in Washington was still seen as hostile in the region. The Syrian Defense Ministry called the attack a “blatant air aggression,” not addressing the fact that the government of Bashar Assad had let these militias operate from territory it ostensibly controls. Iraq’s government, which Washington has been trying not to destabilize, said that 16 people had been killed and 25 wounded on its territory, and that the attacks were “a threat that will drag Iraq and the region into unforeseen consequences.”

But the Iranians themselves were slow to respond, and even then, they pointed to the war in Gaza, not the U.S., as the culprit. In a statement, Kanaani said that the “roots of the tension and crisis in the region go back to the occupation by the Israeli regime and the continuation of this regime’s military operations in Gaza and the genocide of the Palestinians with the unlimited support of the U.S.”

And when Kataib Hezbollah, a group that U.S. intelligence believes was involved in the deadly Jordan attack, declared earlier this week that it would no longer target U.S. forces, it made clear that it was pressured by Iran and Iraq — and wasn’t happy about it.

It was a revealing moment about the two strategies that Iran appears to be pursuing. The first is a short-term approach related to the war in Gaza, where proxies have opened multiple fronts against Israel and escalated attacks on U.S. bases to pressure Washington, which they see as Israel’s backer, to get a cease-fire. One senior American official noted recently that when a brief pause was declared in November and hostages were exchanged, the proxies suspended their attacks.

But there is a longer-term aim by Iran: to drive Americans out of the region with the help of its proxies in Iraq and Syria.

“This is not an all-or-nothing moment for Iran; this is just one dot on a much longer plotline of Iran’s strategic agenda in the Middle East,” said Afshon Ostovar, an associate professor of national security affairs at the Naval Postgraduate School in Monterey, California, and an expert on Iran’s military. “Iran can suffer as many Iraqi and Syrian casualties as it likes,” he said. “It doesn’t feel compelled to respond to the deaths of proxy militants. But if Iranians are killed, it’s different.

“For Iran, this is a long war, not a short war, and this has nothing to do with Gaza,” Ostovar said. It is, he said, “about Iran’s steady, long march across the Middle East to push out U.S. forces and weaken U.S. allies.”

The evidence of the past few years suggests that military action by the U.S. may degrade capabilities, but it does not create long-term deterrence. After the drone strike that killed Soleimani, Trump claimed it would stop Iran and its proxies from attacking Americans and their allies. It led to a pause but not a halt.

Negotiation has done more, but not much more. When the U.S. and Iran, through indirect negotiations that involved Oman and Qatar, negotiated last year for the release of $6 billion in frozen oil revenues in exchange for a detainee swap, attacks on U.S. bases in Iraq and Syria diminished significantly.

But that fell apart after Hamas attacked Israel on Oct. 7, resulting in roughly 1,200 Israeli deaths and setting off the war in Gaza. Iran and its proxies have maintained that if a permanent cease-fire is reached in Gaza, things will again quiet down. But it is still unclear whether the cease-fire or even another temporary pause can be negotiated. And the history of the Middle East suggests the quiet may not be long-lived.
